DETAILED DESCRIPTION

[0051] The following will be described in detail in combination with the accompanying drawings Figures 1-9 The present application will be further described in detail.

[0052] As Figure 1 and Figure 2As shown, the application discloses a containing box for containing material bags. The containing box comprises side plates 1, a bottom plate 2, a hanging plate 3 and a bag opening support plate. The side plates 1 are provided in plurality, and the plurality of side plates 1 are arranged to form a polygonal frame. In the embodiment, four side plates 1 are provided, and the four side plates 1 are arranged to form a square frame, and cooperate with the bottom plate 2 to form a containing space for containing the material bags. The connecting end of the bottom plate 2 is rotatably connected to the bottom edge of the side plate 1, and the movable end of the bottom plate 2 can be closed to carry the material bags, or the movable end of the bottom plate 2 is opened to make the material bags out of the containing box. The bottom plate 2 can be provided in two, and the two bottom plates 2 are respectively connected to the bottom ends of two opposite side plates 1, so that the two bottom plates 2 can be cooperatively opened or closed. The connecting end of the bottom plate 2 can be connected to the side plate 1 through a rotating shaft, so as to realize the overturning of the bottom plate 2.

[0053] The side edge of the bottom plate 2 is inclined at a preset angle, so that when the two bottom plates 2 are closed, the side edge of the bottom plate 2 can leave a gap between the side plate 1, reducing the risk of interference between the bottom plate 2 and the side plate 1 when the bottom plate 2 is closed, and ensuring that the two bottom plates 2 can be reliably closed. The side edge and the movable end of the bottom plate 2 can be provided with a rounded corner, reducing damage to the material bags and optimizing the use effect.

[0054] As shown in Figure 1 and Figure 2 , the hanging plate 3 is arranged on the outer side of the side plate 1, and is used for erecting the containing box. The hanging plate 3 can be provided in two, and the two hanging plates 3 are arranged on the outer sides of the two opposite side plates 1, so that the containing box is erected by fixing the two hanging plates 3, and the bottom plate 2 on the lower side can be overturned and opened, and the material bags are out of the containing box.

[0055] The bag opening support plate comprises a first support plate 4 and a second support plate 5, the lower end of the first support plate 4 is connected to the upper end of the side plate 1, and the second support plate 5 is connected to the side edge of the first support plate 4. The bag opening support plate can support the bag opening, the first support plate 4 plays a role in opening the bag opening, and the two second support plates 5 can optimize the bag opening effect while avoiding damage to the bag opening, reliably completing the bagging and filling process. The containing box carries the material bags to realize the bagging, oil filling and sealing operation in the oil production process, which can reduce the difficulty of bagging. Since no paper box is used in this operation, paper dust will not enter the oil, thereby reducing the pollution risk, improving the cleanliness of the oil packaging process, improving the quality of the oil, and facilitating the transfer of the material bags to the paper box.

[0056] As shown in Figure 1 and Figure 2 , the containing box is provided with at least two handles 6, and the handles 6 can be arranged on the side surface of the side plate 1 adjacent to the hanging plate 3. The handles 6 can be symmetrically arranged on both sides of the containing box to facilitate manual or mechanical driving of the containing box. The specific position, size and shape of the handle 6 are set according to actual needs.

[0057] The holding box can be made of polypropylene plastic. Food-grade polypropylene plastic can ensure the food safety of oil and fat, and the holding box made of polypropylene plastic can reduce the weight and facilitate transportation.

[0058] As shown in Figure 1 and Figure 2 , the size of the holding box can be set as needed to meet the reliable placement of the material bag and to move the material bag into the carton. The holding box can be the same size as the carton or slightly smaller than the carton to facilitate the removal of the material bag into the carton.

[0059] The implementation principle of the holding box according to an embodiment of the present application is that: the side plate 1 and the bottom plate 2 form a containing space, so that the material bag can be placed in the holding box; when the bag is sleeved, the first support plate 4 supports the bag opening to facilitate subsequent oil filling, and at the same time, the second support plate 5 can optimize the support effect of the bag opening during bag sleeving, and the second support plate 5 can reduce the hooking of the edge of the first support plate 4 to the material bag, thereby reducing the damage to the material bag.

[0060] As shown in Figure 3 and Figure 4 , the present application further discloses a packaging replacement device (hereinafter referred to as "device") which cooperates with the above-mentioned holding box 50 to move the material bag in the holding box 50 into the carton 60. The device comprises a main frame 10, a conveying mechanism and a supporting mechanism.

[0061] The main frame 10 comprises an upper layer 11 and a lower layer 12, and the upper layer 11 and the lower layer 12 are respectively used for placing the holding box 50 and the carton 60. The conveying mechanism comprises a first conveying assembly and a second conveying assembly 21, and the first conveying assembly is used for conveying the holding box 50 to the upper layer 11, and the second conveying assembly 21 is used for conveying the carton 60 to the lower layer 12. The supporting mechanism comprises a side supporting assembly 31 and a bottom supporting assembly 32, the side supporting assembly 31 is arranged on both sides of the conveying direction of the upper layer 11, and the side supporting assembly 31 is used for cooperating with the hanging plate 3 to support the holding box 50 on the upper layer 11; the bottom supporting assembly 32 is rotationally connected to the main frame 10, and the bottom supporting assembly 32 is used for cooperating with the bottom plate 2 to switch the movable end of the bottom plate 2 to a closed state or to switch the movable end of the bottom plate 2 to an open state.

[0062] As shown in Figure 3 and Figure 4As shown, the main frame 10 provides a support frame, the first conveying assembly conveys the containing box 50 to the upper layer 11, and the containing box 50 is erected on the main frame 10 by the side supporting assembly 31, at this time the bottom plate 2 is carried by the bottom supporting assembly 32. The second conveying assembly 21 conveys the carton 60 to the lower layer 12, and the containing box 50 is positioned corresponding to the carton 60, so as to facilitate the transfer of the bags. When the bags are transferred, the bottom supporting assembly 32 drives the bottom plate 2 to open. Since the device is arranged such that the containing box 50 and the carton 60 are arranged vertically in space, the bags can be vertically dropped from the containing box 50 into the carton 60, so that the bags can be reliably and conveniently transferred, and the carton 60 does not participate in the bagging, grease filling and bag sealing operations, which helps to improve the problem of grease contamination and also enables the bags to be transferred into the carton 60.

[0063] The first conveying assembly can be a slide rail and a pair of clamping jaws, the two clamping jaws are driven to move by the slide rail, and the two clamping jaws can be respectively matched with the handles 6 on both sides of the containing box 50 to realize the movement of the containing box 50, so as to move the containing box 50 containing the bags from the previous work station to the preset position of the upper layer 11, and move the containing box 50 after the bags are transferred out of the preset position. It can be understood that when the first conveying assembly moves the containing box 50, it can provide horizontal pushing and pulling force for the containing box 50, so that the bottom plate 2 will not be accidentally opened; the preset position of the upper layer 11 can be the same height as the previous work station of the containing box 50 or slightly lower than the previous work station in the vertical direction, so as to ensure that the bottom plate 2 remains closed during the movement process, and the movement of the bags is stably realized.

[0064] As shown in Figure 3 and Figure 4 The second conveying assembly 21 can be a conveying roller assembly to convey the empty carton 60 to the preset position of the lower layer 12, and to move the carton 60 containing the bags out of the preset position of the lower layer 12. Since the carton 60 used includes a plurality of different sizes, the second conveying assembly 21 can also include a lifting cylinder. The lifting cylinder is arranged below the carton 60 at the lower layer 12 of the main frame 10, so that after the carton 60 is moved to the preset position of the lower layer 12, the height of the carton 60 can be adjusted, so as to avoid the vertical height between the carton 60 and the containing box 50 being too large due to the low height of the carton 60, which causes the dropping path of the bags to be lengthened, affecting the stability of the carton 60 containing the bags.

[0065] As shown in Figure 3 and Figure 4 Optionally, the second transmission assembly is provided with a limiting piece 211, the limiting piece 211 includes a rotating shaft part 2111 and a limiting part 2112, the two ends of the rotating shaft part 2111 are connected to the main frame 10 on the opposite sides along the conveying direction of the carton 60, and the limiting part 2112 is arranged on the rotating shaft part 2111, the rotating shaft part 2111 drives the limiting part 2112 to rotate, so that the limiting part 2112 is arranged horizontally or vertically.

[0066] The limiting member 211 is arranged on one side of the preset position of the lower layer 12, and can prevent the carton 60 from continuing to advance. When the shaft part 2111 drives the limiting part 2112 to be arranged horizontally, the carton 60 can be conveyed to the next station, and when the limiting part 2112 is arranged vertically, the movement of the carton 60 can be limited, so as to ensure the positioning and stability of the carton 60 in the process of transferring the bags. The limiting part 2112 can be a plate structure, and the horizontal and vertical conversion can be realized by rotating the shaft part 2111. When the limiting part 2112 is arranged horizontally, the upper surface thereof is flush with or slightly lower than the lower surface of the carton 60, so that the carton 60 can be smoothly conveyed to the next station.

[0067] As shown in Figure 5 and Figure 6 , the side supporting assembly 31 can be two oppositely arranged supporting plates 311, which support two hanging plates 3 respectively, so as to support the containing box 50. Alternatively, the bottom supporting assembly 32 includes two oppositely arranged turnover members 321, which are arranged on both sides of the conveying direction of the containing box 50. One end of the turnover member 321 is rotationally connected to the main frame 10, so that the two turnover members 321 are relatively opened or closed. The other end of the turnover member 321 is provided with a plurality of protruding parts 3211. When the turnover member 321 is closed, the protruding parts 3211 of the two turnover members 321 are arranged staggeredly.

[0068] The protruding parts 3211 at the ends of the two turnover members 321 are arranged staggeredly, and the staggered arrangement can increase the support path length of the falling bags in the vertical direction during the turnover, so that the bags can still be supported by the turnover members 321 in the initial stage of the falling process, thereby slowing down the falling speed of the bags and improving the stability of the bag transfer. The turnover member 321 can be made of polypropylene plastic, so as to ensure the food safety.

[0069] As shown in Figure 5 and Figure 6 , alternatively, the bottom supporting assembly 32 further includes a hydraulic cylinder 322, one end of which is connected to the main frame 10, and the other end of which is connected to the turnover member 321.

[0070] The hydraulic cylinder 322 is connected to the end of the turnover member 321 away from the protruding part 3211, so as to make the end of the turnover member 321 provided with the protruding part 3211 turn downward by the jacking of the hydraulic cylinder 322. The jacking stability of the hydraulic cylinder 322 is good, which can improve the stability of the opening and closing of the turnover member 321, and the repositioning and closing of the turnover member 321 can be realized by the contraction of the hydraulic cylinder 322.

[0071] As shown in Figure 5 and Figure 6As shown, the packaging replacement device further comprises a clamping mechanism. The clamping mechanism comprises a vertical moving assembly 41 arranged on the main body frame 10, and a clamping assembly 42 connected to the movable end of the vertical moving assembly 41. The clamping assembly 42 is used to clamp the bag opening of the material bag, and can move downward under the driving of the vertical moving assembly 41 after clamping. The clamping mechanism can provide lifting force when transferring the material bag, reduce the falling speed of the material bag, and improve the stability and reliability of the material bag transfer.

[0072] As shown in Figure 5 and Figure 6 As shown, the clamping assembly 42 comprises a driving part 421 and a clamping plate 422. The driving part 421 is arranged on the movable end of the vertical moving assembly 41, and the driving part 421 is drivingly connected to the clamping plate 422. The clamping plate 422 is driven by the driving part 421 to clamp the bag opening of the material bag.

[0073] As shown in Figure 5 and Figure 6 The driving part 421 drives the clamping plate 422 to achieve clamping effect. When clamping the material bag, the contact area with the material bag can be increased by the clamping plate 422, the reliability of clamping can be improved, and the risk of damaging the material bag can be reduced. The driving part 421 can be an electric rotating shaft. One end of the clamping plate 422 is connected to the movable end of the vertical moving assembly 41 through the electric rotating shaft. The clamping plate 422 can be clamped by electric control. In order to achieve clamping effect, the width of the movable end of the vertical moving assembly 41, the arrangement position of the electric rotating shaft, and the distance between the two clamping plates 422 can be set according to needs. The clamping plate 422 can be made of rubber material to increase the friction force during clamping and ensure the clamping effect. The clamping plate 422 can be provided with a protruding structure to ensure the clamping effect. In order to improve the stability of clamping, an adsorbing structure can be arranged on the clamping plate 422 to reliably clamp the material bag.

[0074] As shown in Figure 5 and Figure 6As shown, the clamping assembly 42 also comprises a motor 423 and a roller 424, the roller 424 is connected to the side of the clamping plate 422, and the motor 423 is in transmission connection with the roller 424. Connection structures can be arranged on both sides of the clamping plate 422, so that the motor 423 and the roller 424 are arranged on the connection structures. In order to avoid interference, the clamping plate 422 or the connection structures on both sides can protrude in the horizontal direction from the movable end of the vertical moving assembly 41. The motor 423 drives the roller 424 to rotate, and by arranging the position of the roller 424, the roller 424 can contact the bag before the clamping plate 422, so that the rotation of the roller 424 can guide the bag, and the bag opening is vertical, so as to facilitate the clamping of the clamping plate 422. It can be understood that the device also has a control box, and the control system of the control box controls the movement of each structure to ensure the normal replacement of the package. The action control of the device can be realized by using a PLC control cabinet, so that the device can cooperate with the original oil sealing production line.

[0075] The implementation principle of the packaging replacement device in the embodiment of the application is as follows: the first conveying assembly moves the containing box 50 containing the bags to the preset position on the upper layer 11 of the main body frame 10, and the second conveying assembly 21 conveys the carton 60 to the preset position on the lower layer 12. At this time, the supporting plate 311 bears the hanging plate 3, the turnover piece 321 bears the bottom plate 2, and the limiting part 2112 is vertical to block the carton 60 from continuing to move forward. After the containing box 50 is aligned with the carton 60, the vertical moving assembly 41 moves downward, so that the clamping assembly 42 can clamp the bag opening. The turnover piece 321 is turned over, so that the bag falls, and the vertical moving assembly 41 continues to move downward, so that the bag stably falls into the carton 60, that is, the transfer of the bag is completed.

[0076] As shown in the drawings, Figure 7 The embodiment of the application also discloses an oil sealing production line (hereinafter referred to as a "production line"), which comprises a carton bottom sealing device 200, an oil bag packaging device 300 and a carton sealing device 400 which are distributed in a U shape. The carton bottom sealing device 200 and the carton sealing device 400 are respectively arranged on opposite sides of the U shape.

[0077] The production line also comprises a plurality of the above-mentioned packaging replacement devices 100, which are arranged on the inner side of the U shape and are connected between the opposite sides of the U shape. The oil bag packaging device 300 is used for bagging, filling and sealing the bags in the containing box 50. The upper layer 11 is connected with the oil bag packaging device 300 through a first conveying device 510 to form a closed loop, so as to drive the containing box 50 to pass through the oil bag packaging device 300. The lower layer 12 is connected with the carton bottom sealing device 200 and the carton sealing device 400 through a second conveying device 520 to convey the carton 60 from the carton bottom sealing device 200 to the carton sealing device 400. The packaging replacement device 100 of the production line is provided in plurality, so that the transfer of a plurality of bags can be completed at the same time, and the production efficiency is improved.

[0078] As shown in Figure 7 , the oil bag packaging device 300 includes a bagging mechanism 310, a filling mechanism 320, and a sealing mechanism 330. During processing, the holding box 50 is transported by the packaging replacement device 100 to the bagging mechanism 310 for bagging, then transported to the filling mechanism 320 to fill the oil into the bag, and then transported to the sealing mechanism 330 to seal the bag. Since the paper box does not participate in the process of bagging, filling oil, and sealing, the problem of paper dust pollution of oil on the production line can be improved.

[0079] As shown in Figure 7 , the paper box bottom sealing device 200, the oil bag packaging device 300, and the box sealing device 400 are arranged in a U shape, and the packaging replacement device 100 can communicate with the opposite sides of the U shape. The upper layer 11 of the packaging replacement device 100 forms a closed loop transportation with the oil bag packaging device 300 through the first conveying device 510, so as to complete the bagging, oil filling, and bag sealing operations through the holding box 50. This process does not involve paper boxes, so there is no problem of paper dust entering the oil and causing pollution. The lower layer 12 of the packaging replacement device 100 communicates with the paper box bottom sealing device 200 and the box sealing device 400 through the second conveying device 520, so as to place the bag in the bottom-sealed paper box 60 and seal the box. The holding box 50 and the paper box 60 are transported on different conveying lines, which can reduce the risk of pollution. Moreover, since the packaging replacement device 100 is arranged on the inner side of the U shape, and the holding box 50 and the paper box 60 are arranged above and below in the packaging replacement device 100, the production line can realize bag replacement while not increasing the space occupation on the outer side of the U shape, saving the floor area and effectively utilizing the space.

[0080] The first conveying device 510 and the second conveying device 520 can be a conveying roller structure, which can respectively transport the holding box 50 and the paper box 60 between different stations.

[0081] As shown in Figure 8 and Figure 9 , optionally, the production line further includes a bagging device 600 arranged on one side of the packaging replacement device 100, so that the holding box 50 is transported from the bagging device 600 to the packaging replacement device 100. The bagging device 600 includes a support frame 610, a horizontal sliding rail 620, a vertical sliding rail 630, and an anti-static clamp plate 640. The fixed part of the horizontal sliding rail 620 is connected to the support frame 610, the fixed part of the vertical sliding rail 630 is connected to the movable part of the horizontal sliding rail 620, and the anti-static clamp plate 640 is connected to the movable part of the vertical sliding rail 630. After the anti-static clamp plate 640 clamps the bag opening of the bag, the bag opening of the bag is vertically arranged.

[0082] The anti-static clamp plate 640 can be moved to the bag opening of the material bag under the driving of the horizontal slide rail 620 and the vertical slide rail 630, the material bag is clamped by the anti-static clamp plate 640, the influence of static electricity is reduced, the vertical degree of the bag opening is optimized, and reliable clamping of the material bag by the subsequent clamping assembly 42 is facilitated. It can be understood that the vertical slide rail 630 and the anti-static clamp plate 640 of the whole bag device 600 need to be provided in two groups and be arranged on the two sides of the conveying direction of the containing box 50, so as to realize clamping of the bag opening by the cooperation of the two anti-static clamp plates 640.

[0083] As shown in Figure 8 and Figure 9 The top end of the support frame 610 of the whole bag device 600 is arranged above the conveying line and can be moved from top to bottom to realize clamping of the bag opening of the material bag. The vertical movement of the anti-static clamp plate 640 is realized by the vertical slide rail 630, and the movement of the anti-static clamp plate 640 along the direction perpendicular to the conveying direction is realized by the horizontal slide rail 620, so that the two anti-static clamp plates 640 can realize pre-clamping of the bag opening of the material bag and drive the bag opening upward, and the vertical degree of the bag opening is improved. The double arrangement and guiding of the material bag can be realized with the roller 424. Since the material bag is made of plastic, in order to alleviate the influence of static electricity on the vertical degree of the bag opening during the whole bagging process, the whole bag device adopts an anti-static clamp plate to optimize the whole bagging effect. It should be noted that the clamping force of the whole bag device 600 is smaller than the clamping force of the clamping assembly 42, and the whole bag device 600 will not drive the whole material bag to move, but only the bag opening will be straightened, so as to straighten the bag opening and provide favorable conditions for clamping of the clamping assembly 42. In order to ensure the whole bagging effect, the lowest height of the movement of the anti-static clamp plate 640 can be lower than the lowest height of the movement of the clamping assembly 42.

[0084] The implementation principle of the oil encapsulation production line in the embodiment of the present application is as follows: the containing box 50 is conveyed by the packaging replacement device 100 to the bagging mechanism 310 for bagging, and then sequentially passes through the filling mechanism 320 for oil filling and the sealing mechanism 330 for material bag sealing, and then passes through the whole bagging device 600 for whole bagging, and is conveyed back to the upper layer 11 of the packaging replacement device 100; the carton 60 is sealed by the carton bottom sealing device 200, is conveyed to the lower layer of the packaging replacement device 100, and is transferred by the packaging replacement device 100, so that the material bag is moved from the containing box 50 to the carton 60, and then the carton 60 containing the material bag is conveyed to the carton sealing device 400 for carton sealing, that is, one oil encapsulation process is completed.

[0085] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
